Full-occupancy annual rent. Vacancy comes off this number.
Texas real estate property management math cheat sheet
Built for Texas sales agent exam prep. Use this to build the operating budget in order: gross potential rent, vacancy, effective gross income, operating expenses, and net operating income.
Vacancy and collection loss is subtracted from gross potential rent.
Add other income such as laundry, parking, or fees after subtracting vacancy.
NOI excludes the mortgage payment and income taxes.
Usually a percent of rent actually collected, applied after vacancy.
Occupancy and vacancy total 100%.
The exam setup rule
- Find gross potential rent: units times monthly rent times 12.
- Subtract vacancy and collection loss.
- Add other income for effective gross income.
- Subtract operating expenses for net operating income.
- Apply the management fee to collected rent unless told otherwise.
Five worked examples
10 x 1,200 x 12 = $144,000 gross potential rent.
144,000 - 7,200 = 136,800 collected. Plus 6,000 = $142,800 effective gross income.
142,800 - 48,000 = $94,800 net operating income.
136,800 x 0.08 = $10,944 management fee.
94,800 / 0.08 = $1,185,000 value by the income approach.
Traps to check
- Do not subtract the mortgage payment to find NOI.
- Do not add other income before subtracting vacancy from rent.
- Do not apply the management fee to gross potential rent when the stem says collected rent.
- Do not forget to annualize monthly rent.
- Do not include income taxes or depreciation in operating expenses for NOI.
Sanity check
- Effective gross income is always less than gross potential rent when there is vacancy.
- NOI is income minus operating expenses only, before financing.
- Higher vacancy lowers collected rent, effective gross income, and NOI.
